    摘要: A filter system including a method for self cleaning the filter system of an electronic equipment enclosure where air flow is monitored either by monitoring fan performance of air flow velocity through the enclosure. The system includes two filters elements, an upstream ASHRAE or HEPA filter element to block particulate matter and a downstream PTFE filter element to block water vapor. The ASHRAE or HEPA filter element is relatively inexpensive and easy to clean. The PTFE filter element is more expensive and difficult to clean. Thus, the cheaper filter is used to protect the more expensive filter from contaminants and to increase its useful life. The method of self cleaning includes stopping the fan when a signal is received indicating a predetermined resistance to air flow which is a function of blockage of the filter elements, thereafter operating the fan at an increased rotational velocity to determine whether the fan itself is malfunctioning, thereafter slowing and stopping the fan to allow the fan to be reversed, rotating the fan in reverse for a predetermined period of time, such as five minutes, thereafter slowing and stopping the fan and returning the fan to its usual rotational velocity and direction. If the resistance to air flow is still above a predetermined level, the fan is again slowed, stopped and reversed and then returned to normal operation. The reversal operation can be conducted a multiple number of times, however, after a predetermined number, a signal is sent requesting maintenance

    摘要: A method of desorbing a volatile component from a spent adsorbent is disclosed, which includes flowing a stream of supercritical carbon dioxide through a rotating packed bed of the spent adsorbent; and collecting an effluent from the rotating packed bed, which contains supercritical carbon dioxide and the volatile component entrained therein. In one embodiment of the present invention a spent activated carbon from a process for recovering 2,2,3,3-tetrafluro-1-propanol from a gas stream containing 2,2,3,3-tetrafluro-1-propanol is regenerated by flowing a stream of supercritical carbon dioxide through a rotating packed bed of the spent activated carbon.

    摘要: Toxic substances such as heavy metals are extracted from a medium using a sorbent composition. The composition is derived by sulfidation of red mud, which contains hydrated ferric oxides derived from the Bayer processing of bauxitic ores. Exemplary sulfidizing compounds are H2S, Na2S, K2S, (NH4)2S, and CaSx. The sulfur content typically is from about 0.2 to about 10% above the residual sulfur in the red mud. The sulfidized red mud is effective for sorbing some contaminants, such as mercury, which are not effectively sorbed by red mud. Conversely, red mud is effective for sorbing other contaminants, such as arsenic, which are not effectively sorbed by sulfidized red mud. Thus, some aspects of the invention utilize combinations of red mud and sulfidized red mud, which potentially can allow for the extraction of a wider range of contaminants.

    摘要: Methods and apparatus for purifying gases having organic impurities, including the use of granulated porous glass. The method of the invention includes the following steps. An impure gas comprising a first gas and an organic compound is provided. A packed bed of granulated porous glass is provided. The impure gas is allowed to flow into the packed bed, thereby preferentially adsorbing at least some of the organic compound on the granulated porous glass to yield a purified gas having a concentration of the organic compound that is lower than that of the impure gas. The purified gas is allowed to flow out of the packed bed.
